Supported platforms

Platform features

Note: Each platform refers to generating output - inference - differently: OpenAI uses "Response", Gemini uses "Interaction", and Anthropic uses "Message". I've decided the word "Query" best represents how you interact with a generative LLM: you compile a query and then run the query to generate a response. The word "Embedding" will continue to be used for embedding models.

To generate a response, you must first compile a query. A query is made up of different input components: text prompts, files, a JSON schema, and/or system instructions. Once the query is compiled, it can be sent to the LLM for inference.

This library allows you to compile a query before sending it to the model for two reasons:

1. You can log/analyze the request payload before sending it.
2. You can compile individual requests for batching.
